Volcano eruption in Iceland

volcano eruption in iceland

A major volcanic eruption is expected in Iceland, although the timing is unknown. Seismic activity in the southwestern region of the island has persisted since late October, and previous eruptions have occurred in the same area, the most recent taking place during the summer. However, experts are concerned that this time, due to the large tracts of land that have been opened up. The eruption of volcano in iceland It is imminent.

Therefore, we are going to update you on the possible eruption of the volcano in Iceland.

In the southwestern region of the island, the ground began to shake on October 24. This is not uncommon in a country with over 200 active volcanoes and does not have a huge impact on the daily lives of Icelanders. However, the frequency of Small earthquakes have been increasing and now exceed 1.000 per day. This is known as a seismic swarm, a phenomenon that occurred on a smaller scale before the eruption of La Palma in September 2021. Authorities fear that one of the volcanoes in the area could erupt, but it is also possible that it is simply a temporary fact.

Ármann Höskuldsson, a volcanologist at the University of Iceland, points out that most earthquake swarms end without an eruption, with only cracks and faults. However, it is clear that this is the beginning of a major tectonic event that will release the tension that has been building on the peninsula over the past 800 years.

Origin of the volcano eruption in Iceland

The town of Grindavík, located in the southwest of Iceland on the Reykjanes peninsula, is at the epicenter of a series of earthquakes that have been occurring over a wide area. Initially, the seismic swarm was concentrated to the west of the affected region, but then moved eastward. During the weekend, the earthquakes changed direction again and were concentrated further south of Grindavík. This change was so significant that if an earthquake occurred at that point, it could result in an underwater eruption.

At the beginning of seismic activity, earthquakes occurred at depths greater than five kilometers. However, On Thursday the tremors were already occurring at 3,5 kilometers and in recent days they have occurred at just 800 meters.

After closely monitoring the seismic swarm and the shift in the hypocenter, the Icelandic Meteorological Office (IMO) and other experts have concluded that a massive magma intrusion is occurring. The size of this magma intrusion is expected to be immense and reach the entire area. According to Bill McGuire, emeritus professor of geophysical and climate hazards at University College London, models indicate that magma is rising along a fracture 15 kilometers long and is now approaching the surface, perhaps less than 800 meters. Satellite GPS data shows that the terrain in several parts of the region is rising several centimeters each day.

Where will the magma appear?

The place of magma appearance remains a mystery to scientists. However, the fracture formed, which extends from the southwest to the northeast, provides a crucial clue. The Icelandic Meteorological Office (IMO) has suggested that magma will most likely emerge at some point in the rift. This event is believed to be related to the nearby Fagradalsfjall volcano, whose activity has been gradually increasing since 2021. Its last eruption took place in the summer.

As a result, material may come to the surface at this location. The only unknown factor is the timing. In its latest reports, the IMO has stated that “there is a high probability that a volcanic eruption will occur in the coming days.

Experts do not know the place of appearance and the type of molten earth, which leaves several possibilities open. Unlike typical conical volcanoes, the relatively flat area of ​​the island, such as Fagradalsfjall, is prone to having volcanic fissures where the land opens up. Then, Lava flows from a point within the crack and is not necessarily explosive in nature.

If the lava flows south of the fissure, it would reach the sea. However, an explosive eruption at a non-cracked point cannot be ruled out. Professor Höskuldsson points out that basaltic lava characterizes volcanism in Iceland. This gives rise to mild eruptions that generate lava flows, which could flow faster than those on La Palma.

Doubts among the population about a volcano in Iceland

There is a common query about the frequency of earthquakes and volcanic eruptions in Iceland. The region experiences this type of phenomena at a higher rate than other parts of the world, and this can be attributed to its unique geographic location. Iceland sits on two tectonic plates, the North American Plate and the Eurasian Plate, which continually move apart, causing constant volcanic activity and seismic tremors. This phenomenon is further amplified by Iceland's location in the Mid-Atlantic Ridge, where the Earth's crust is particularly thin, making it more susceptible to eruptions and earthquakes.

In the middle of the North Atlantic, there is a point where the North American tectonic plate and the Eurasian tectonic plate appear to meet. However, this is not a meeting of the two plates, but rather a separation as both plates move away from each other. This process has led to the formation of the mid-Atlantic ridge, a huge fissure that runs from south to north along the ocean floor. Although the fissure is located thousands of meters under the sea, it also runs through Iceland, dividing the country into two parts.

As you can see, the tension right now is quite high. I hope that with this information you can learn more about the volcano in Iceland and its possible eruption.
